Prince Edward Island had felt the earthquake; the intensity was rated at the time at IV (Slight tremor) – VI (Strong tremor) on the Rossi-Forel scale. Long before the coast was reached wreckage was met, mute evidence of the disaster which had befallen the region. Note the masts of a submerged sailing ship in the bay, possibly the Port au Bras harbour. Analyses of the 1929 Grand Banks tsunami indicate that it was generated by the large slope failure rather than by the earthquake itself (Murty, 1977, Clague, 2001). A.

[6], In 1952, American scientists from Columbia University put together the pieces of the sequentially broken cables that led to the discovery of the landslide and the first documentation of a turbidity current. The quake’s epicentre was located about 400 kilometres south of the Grand Banks of Newfoundland. Cleanup along the shore. 4, p. 1003-1020. "As recently as 1929, there was a tsunami that impacted Nova Scotia and Newfoundland." One general merchandise store, 9 x 17 metres, was moved 60 metres inland and deposited in a meadow, with all its stock left intact on the shelves. [citation needed] The occurrences of large tsunamis, such as the one in 1929, are dependent upon deposition of sediments offshore because it was the landslide that made the tsunami so powerful.

The earthquake triggered a large submarine slump (an estimated volume of 200 cubic kilometres of material was moved on the Laurentian slope) which ruptured 12 transatlantic cables in multiple places (locations of cable breaks can be seen as small red triangles on the isoseismal map) and generated a tsunami (a large induced sea wave).
